detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. based on All other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present invention.

With the evolution of technology, there are several cases of the number of antennas of the intelligent terminal, which are mainly used to improve the performance of wireless communication. However, the isolation of each antenna needs to be considered between multiple antennas of the intelligent terminal, and the interconnection between the antennas must be ensured. The isolation of the multi-antenna is at least 10 dB, and the smart terminal is faced with various strict wireless module coexistence scenario authentication tests to ensure the final antenna function of the whole device. The embodiment of the present invention provides an implementation manner of adaptive switching of multiple antennas. In the following embodiments, three antennas will be taken as an example. When the terminal device has more antennas, those skilled in the art can use the implementation manners provided by the various embodiments of the present invention without any creative work. Achieve similar solutions and achieve similar technical effects.

As shown in FIG. 1 , in the prior art, the smart terminal mainly includes three parts: a primary antenna, a diversity antenna, and a WIFI and a GPS antenna. Generally, the front end module 1 is connected to the main antenna through the physical contact C1, the front end module 2 is connected to the diversity antenna through the physical link C2, and the front end module 3 is connected to the WIFI/GPS antenna through the physical link C3, each antenna One-to-one correspondence with a front-end module; optionally, the front-end module may also have other corresponding relationships with the antenna: for example, multiple front-end modules correspond to one antenna module; for example, a 2G/3G/4G module of cellular communication corresponds to the same antenna module; Alternatively, one front end module corresponds to multiple antenna modules; for example, LTE (Long Term Evolution of Universal Mobile Communication Technology) module corresponds to one or more of a high frequency antenna module, a low frequency antenna module, and an intermediate frequency antenna module.

In order to solve the contradiction between the demand of multiple antennas and the isolation between multiple antennas of intelligent terminals, the existing solution is to solve this contradiction through the architecture design of the radio frequency circuit.

As shown in FIG. 2, an intelligent terminal provided with an adaptive antenna switching system includes: a plurality of front end modules 501, a plurality of antenna modules 503, and electrical connections with a plurality of front end modules and a plurality of antenna modules, respectively. An Antenna Matrix Management Switch Module (AMMSM) 502.

In the present invention, the plurality of front-end modules 501 of the smart terminal in the present invention are functional modules having no application functions in the smart terminal, for example, a call module, a data internet module, a WIFI communication module, a GPS positioning module, and the like. The antenna module of the same or different performance is included in the present invention, and the average intensity of all the antenna modules is different in the same time period.

In order to ensure the degree of freedom of antenna module switching, the present invention first determines that each antenna module of the intelligent terminal can meet the over-the-air technology index standard of each front-end module, and can effectively implement the self-adaptive module module. Adapt to the switch.

Example 1

As shown in FIG. 3, an adaptive antenna switching method is applied to an adaptive antenna switching system. The system can be set on a smart terminal such as a smartphone, a tablet, or a wearable device, and the method includes:

S1. Acquire a first antenna module corresponding to the first front end module.

S2. When the first antenna module meets the switching condition, the first front end module and the first antenna module match each other, and perform data interaction through the first antenna module.

The first front end module is a front end module selected from the first set according to the first selection rule; the first antenna module is an antenna module selected from the second set according to the second selection rule; the first set is all front end modules The set; the second set is a collection of all antenna modules.

In this embodiment, the first selection rule is to select the front-end module with the highest current priority according to the priority order of the front-end module; the second selection rule is to select the antenna module with the highest current priority according to the priority order of the antenna module.

The above is an adaptive antenna switching method provided by Embodiment 1 of the present invention. According to this embodiment, the first front end module and the first antenna module used by the current user are calculated according to the scene state currently used by the user; In the case of the switching condition, the first front end module and the first antenna module are matched with each other, and data interaction is performed by the first antenna module. In the embodiment, the above-mentioned technical solution is adopted, and the smart terminal adaptively switches the antenna according to the scenario currently used by the user, and ensures that the antenna module of the first front-end module used by the user has The optimal performance greatly improves the user experience.

Embodiment 1 above shows a scheme in which a front-end module is matched with an antenna module, and finally data interaction is completed. It is conceivable that when there are multiple front-end modules and multiple antenna modules in the system, and based on the first selection rule After the first front-end module (ie, the first antenna module above) is matched with the first-order antenna module (ie, the first antenna module above) in the second selection rule, other front-end modules and antennas are needed. The modules are matched one by one, and the matching mechanism is similar to that of the first antenna module and the first antenna module, which will be described below through Embodiment 2.

Example 2

As shown in FIG. 4, an adaptive antenna switching method is applied to an adaptive antenna switching system, and includes:

S1. Acquire a first antenna module corresponding to the first front end module.

The first front end module is a front end module selected from the first set according to the first selection rule; the first antenna module is an antenna module selected from the second set according to the second selection rule. The first set is a collection of all front end modules; the second set is a collection of all antenna modules. The first selection rule is to select the front-end module with the highest current priority according to the priority order of the front-end module; the second selection rule is to select the antenna module with the highest current priority according to the priority order of the antenna module.

S3. Acquire a second antenna module corresponding to the second front end module.

S4. When the second antenna module meets the switching condition, the second front end module and the second antenna module match each other, and perform data interaction through the second antenna module.

The second front end module is a front end module selected from the third set according to the first selection rule; the second antenna module is an antenna module selected from the fourth set according to the second selection rule; and the third set is the first set. The set of all front-end modules that did not complete the match; the fourth set is the set of all antenna modules in the second set that did not complete the match.

Repeat steps S3 and S4 to complete matching between all front-end modules in the intelligent terminal and the corresponding antenna modules.

It should be noted that, at any time, it is always necessary to sort the antenna modules according to the performance and the priority of the front-end modules. Therefore, there may be a logical relationship between the steps S2 and S3, or may be performed simultaneously. This is not limited here.

The above is an adaptive antenna switching method provided by Embodiment 2 of the present invention. The method calculates and completes the first front-end module and the first antenna module used by the current user according to the scene state currently used by the user. In the case that the first front-end module and the first antenna module are matched with each other and after the data interaction is performed by the first antenna module, other front-end modules and other antenna modules except the first front-end module and the first antenna module are implemented. Matching: First, calculate the front-end module with the highest priority ranking and the antenna module with the highest priority ordering. Secondly, when the switching condition is met, the front-end module with the highest priority ranking is the highest with the current priority. The antenna modules are matched to each other; finally, all the matching communication between the front-end module and the corresponding antenna module is realized. In this embodiment, after all the front-end modules and all the antenna modules are prioritized, one or more front-end modules that meet the switching conditions are matched and communicated with the corresponding antenna modules; under the premise of ensuring user satisfaction, It will greatly affect the power consumption of the intelligent terminal and realize the maximum use of each antenna module.

The embodiment 1 and the embodiment 2 show the implementation of the matching between the front-end module and the antenna module. It should be noted that before the front-end module matches the optimal antenna module, the front-end module has been matched with the antenna module and passed through the antenna module. For the purpose of data interaction, it is necessary to determine whether the antenna module currently used by the front-end module is an optimal antenna module that can be matched to all the antenna modules of the front-end module. To this end, Example 3 below gives a possible implementation.

Example 3

As shown in FIG. 5, an adaptive antenna switching method is applied to an adaptive antenna switching system, and includes:

S01. The first front end module performs data interaction through the third antenna module.

The first front end module is a front end module selected from the first set according to the first selection rule; the first set is a set of all front end modules. The first selection rule is to select the current priority according to the priority order of the front-end module. The front end module; the third antenna module is an antenna module currently used by the first front end module.

Regarding the formulation of the first selection rule in the above embodiment, two possible implementations are given below:

In scheme A1, the first selection rule specifically includes:

First, identify the front-end modules that are in use in all front-end modules.

Specifically, how to determine the state in which the front-end module is in the "in use" manner is various, for example, mode 1: the front-end module currently displayed on the current screen can be identified as "in use"; or, The front-end module that is directly associated with the currently displayed application interface is identified as "in use"; mode 2: obtains the data transmission requirements of all front-end modules, and identifies the front-end module whose demand is greater than a certain threshold as "in use"; mode 3: intelligent All front-end modules being executed in the background of the terminal are identified as "in use" front-end modules.

Second, the priority of the front-end module being used is configured to be highest in the front-end module priority order.

Specifically, if there are multiple front-end modules in use at the same time, it is necessary to further distinguish the priority order between the front-end modules that are being used. Here, a possible implementation manner is given: determining by a preset priority order For example, the priority order of the pre-configured front-end module when using at the same time is call module>WIFI communication module>data internet module>GPS positioning module; if the call module, WIFI communication module, data internet module and GPS positioning module are used at the same time First, the call module is matched with the optimal antenna module in the manner of the foregoing embodiment, and then the WIFI communication module is matched with the optimal antenna module, and the optimal antenna is matched for all but the front-end modules used in advance according to the preset priority order. Module.

It should be noted that there are many possibilities for the pre-configured mode: mode 1, using the factory preset, the priority order of all the front-end modules that have been preset before the smart terminal leaves the factory; mode 2, the user manually configures, due to the specific use Environment or habit, when the user is dissatisfied or unsuitable for the priority level of all front-end modules that have been preset before leaving the factory, the user can re-set all the front-end modules according to their specific use environment or habits; The user-defined priority level determines and determines the highest priority front-end module among all front-end modules that will be in use.

For example, when the user is in the WIFI environment for a long time, and often uses the WIFI module for data communication, the user can set the priority level of the front-end module as follows: WIFI communication module>call module>data network module>GPS positioning module.

Optionally, due to different usage scenarios, the foregoing pre-configured priorities may be switched according to usage policies of different scenarios. For example, according to the moving speed of the smart terminal, it can be divided into a low-speed moving scene and a high-speed moving scene; in the low-speed moving scene, the pre-configured priority is: WIFI communication module>data internet module>call module>GPS positioning module; In the scenario, the pre-configuration priority is: Call Module > Data Internet Module > WIFI Communication Module > GPS Positioning Module. This embodiment includes, and not only includes, a smart terminal for a scene mode, for example, a tunnel mode. Style, rain and snow mode, etc. The state of each antenna module can be detected and recorded in real time. The user can switch and adjust the antenna module and the front-end module in a pre-configured manner or manually configured by the user, thereby improving user experience.

In short, although there are multiple usage scenarios of the smart terminal, in each usage scenario, the front-end module priority level rules are used to prioritize the multiple front-end modules of the smart terminal in real time.

In scheme A2, the first selection rule specifically includes:

First, get the current start time of each front-end module.

The current start time described in this scenario is the point in time at which any front-end module that is running in the background of the smart terminal initially starts running.

Secondly, according to the order of the current start time of each front-end module, the front-end module priority order is sorted from low to high.

For example, when the current usage time of the WIFI communication module, the data internet module, and the GPS positioning module that the user is using is: data internet module, WIFI communication module, and GPS positioning module, the priority order of the front end module is: data internet module <WIFI communication module <GPS positioning module.

In addition, in this solution, if the intelligent terminal determines in the background that the current start time of two or more front-end modules is the same, it determines and determines the priority to be used according to the priority levels of all the front-end modules that have been preset before the smart terminal leaves the factory. The front-end module with the highest priority among all front-end modules.

Figure 6 is a diagram showing the state of the highest priority front-end module. In the cellular communication (Cellular (2G/3G/4G)) mode, if the user turns on the GPS module, the GPS module switches to the current highest priority module; if the GPS module is turned off and the WIFI module is turned on (the WIFI module is turned on means The data connection), the WIFI module will switch to the current highest priority module; if the GPS module is turned off and the WIFI module is turned off, the cellular communication module will switch to the current highest priority module of the system; in Cellular (2G/3G/4G) In the mode, if the user opens the WIFI module and does not open the GPS module, the WIFI module switches to the current highest priority module; if the GPS module is turned on, the GPS module will switch to the highest priority module; if the GPS module is off and the WIFI module When closed, the cellular communication module will switch to the current highest priority module of the system; when the WIFI module or GPS module is the highest priority module of the current system, as long as there is a voice call request (Voice application), the cellular communication module is switched to the current The highest priority module of the system, when the voice call request ends, then the WIFI module or the GPS module will It should switch to the highest priority module.

Referring to FIG. 5, in step S02, it is confirmed that the third antenna module meets the trigger switching condition, and specifically includes:

S02.1, in the sampling period, determining whether the received signal strength value of the third antenna module exceeds an antenna received signal strength threshold or whether a transmit power value of the third antenna module exceeds an antenna transmit power threshold.

S02.2, when the received signal strength value of the third antenna module exceeds the antenna received signal strength threshold or the transmit power value of the third antenna module exceeds the antenna transmit power threshold, it is confirmed that the third antenna module satisfies the trigger switching condition.

In this embodiment, the steps S01-S02 are used to determine whether the antenna module being used by the first front-end module needs to be switched. When the judgment of steps S02.1-S02.2 is satisfied, the first front-end module performs a new antenna module. Match. Steps S01-S02 can provide guarantee for the front-end module to correctly re-match the new antenna module.

Optionally, for S2 in the foregoing embodiment, where a method for determining whether the first antenna module meets the switching condition, a possible implementation manner is as follows:

S2.1A: Determine whether a power difference value between the first antenna module and the third antenna module is greater than or equal to a power difference threshold.

When the power difference value between the first antenna module and the third antenna module is less than the power difference threshold, the first front end module does not satisfy the trigger switching condition, and the first antenna module and the third antenna module continue to perform data interaction, and the operation ends.

S2.2A: When the power difference value between the first antenna module and the third antenna module is greater than or equal to the power difference threshold, determine whether the expected switching time of the first antenna module is less than a threshold period.

The purpose of steps S2.1A-S2.2A is to avoid too frequent switching of the antenna module.

S2.3, when the threshold period is less than the threshold period, confirm that the first antenna module meets the switching condition, the first front end module and the first antenna module match each other, and perform data interaction by using the first antenna module.

Specifically, a possible implementation manner of the second selection rule in the foregoing embodiment is:

According to the average intensity value of all antenna modules in the sampling period, the priority is ranked from high to low to form an antenna module priority order;

The average intensity value of each antenna module is as follows:

In this embodiment, steps S2.1A and S2.2A are specifically as follows:

Where avgRSSI _optim is the average of the received signal strength of the first antenna module during the sampling period, and avgTX _optim is the average of the transmit power of the first antenna module during the sampling period.

The avgRSSI _former is the average value of the received signal strength of the third antenna module in the sampling period, and the avgTX _former is the average of the transmitting power of the third antenna module in the sampling period.

The average intensity value of each antenna module is as follows:

when

When the power difference threshold is used, it is determined whether the expected switching time of the first antenna module is less than a threshold period; wherein the expected switching time T1 is:

Among them, bwt--antenna dwell time.

When the expected switching time of the first antenna module is greater than or equal to the threshold period, the first front end module does not satisfy the trigger switching condition, and the first antenna module and the third antenna module continue to perform data interaction, and the operation ends.

In the present invention, T1 is a detection switching period of the intelligent terminal, and a relatively constant time value. After the intelligent terminal determines the detection switching period, obviously,

The smaller, the larger the bwt.

In this embodiment, the following solution can also be adopted to prevent the antenna module from switching too frequently:

S2.1B: Determine whether a received power level difference value between the first antenna module and the third antenna module is greater than or equal to a received power level difference threshold.

When the received power level difference value between the first antenna module and the third antenna module is smaller than the received power level difference threshold, the first front end module does not satisfy the trigger switching condition, and the first antenna module and the third antenna module continue to perform data. Interaction, the operation ends.

S2.2B, when greater than or equal to the received power level difference threshold, the second determining module determines whether the expected switching time of the first antenna module is less than a threshold period. The judgment standard of this step is completely consistent with the judgment standard of S2.2A.

The following describes the switching mechanism of the three antenna modules by using a specific embodiment. As shown in FIG. 7, if the third antenna module has ΔRSSI>limitR in the sampling period (ΔRSSI is the received signal strength value of the third antenna module, limitR For the antenna to receive the signal strength threshold) or ΔTx Power>limitT (ΔTx Power is the transmit power value of the third antenna module, limitT is the antenna transmit power threshold), the trigger switching condition is satisfied. Referring to FIG. 7 , when the third antenna module is the antenna module x and satisfies ΔRSSIx>limitR or ΔTxPowerx>limitT, the trigger switching condition is met, and the antenna module y is switched, that is, the antenna module y is the first antenna module described above. And so on, when the third antenna module is the antenna module y, the trigger switching condition is satisfied, and the antenna module z is switched, that is, the antenna module z is as above The first antenna module is described; the third antenna module is an antenna module z, and the triggering switching condition is satisfied, and the antenna module x is switched, that is, the antenna module x is the first antenna module described above.

The concept of the handover condition in the foregoing embodiment is actually measured from two dimensions of received signal strength and transmit power. The avgRSSI characterizes the antenna module reception performance index, and the avgTX characterizes the antenna module emission performance index. among them,

For the received switching threshold, ΔavgRSSI=avgRSSI (current sampling period)-avgRSSI (previous sampling period) is greater than the switching threshold to initiate switching of the antenna module; for the switching threshold of the transmission, ΔavgTX=avgTX (current sampling period)-avgTX( The previous sampling period) is greater than the switching threshold to initiate switching of the antenna module, which corresponds to Figure 7. Obviously, the current antenna module state is definitely the best first antenna. In fact, it is the real-time detection whether the antenna performance will exceed the preset threshold. If it exceeds, it will switch to the better performance antenna.

This embodiment provides an implementation manner in which three antenna modules are switched in a specific order. Of course, the present invention also provides a mechanism for antenna back-cutting, which is specifically described with reference to the following embodiments.

Step 100: The first front end module performs data interaction through the third antenna module.

Step 101: Confirm that the third antenna module meets the trigger switching condition phase.

Step 102: Determine whether the received signal strength value of the third antenna module exceeds the antenna received signal strength threshold or the transmit power value of the third antenna module exceeds the antenna transmit power threshold; when one of the above two conditions is met, step 103 is performed, otherwise Go back to step 101.

In step 103, the antenna module determines a handover phase.

Step 104: Determine whether the power difference value between the first antenna module and the third antenna module is greater than or equal to the power difference threshold; when the above condition is met, go to step 105; otherwise, return to step 100.

Optionally, step 104 may be implemented by determining whether a received power level difference value between the first antenna module and the third antenna module is greater than or equal to a received power level difference threshold, and further, when not satisfied When the condition of step 104 is returned to step 100, an antenna back-cutting mechanism is given. Taking FIG. 7 as an example, if the third antenna module is the antenna module x, the first antenna module is the antenna module y, when When the process proceeds to step 104, if the condition of step 104 is not met, the corresponding front end module can switch back to the antenna module x and continue to use the antenna module x for data transmission.

Step 105, an optimal antenna camping phase.

Step 106: Determine whether the expected switching time of the first antenna module is less than a threshold period; when less than, execute step 105; otherwise, return to step 101.

The above is an adaptive antenna switching method provided by this embodiment. First, the first selection rule is used to determine the front end module with the highest priority as the first front end module. Secondly, the second selection rule is used to determine the antenna with the highest priority. The module is used as the first antenna module to determine whether the first front end module needs to be switched to the first antenna module. Finally, when it is determined that the switching needs to be performed, the matching communication with the first antenna module is performed; the communication stability and reliability are improved. This embodiment discloses the priority ordering rules of the front-end module and the antenna module, improves the reliability and stability of the antenna module switching, ensures that frequent invalid switching is not performed, and ensures that one antenna module is significantly better than the other antenna. When the module is in the module (for example, affected by blocking or multipath fading, etc.), the matching communication between the optimal antenna module and the optimal front-end module can be quickly realized.

Example 6

Referring to FIG. 10, in the embodiment, the antenna matrix management switch unit includes: a first determining module 5021, a second determining module 5022, a function sorting module 5023, and an antenna sorting module 5024.

The first front end module performs data interaction through the third antenna module.

The first front end module is a front end module selected from the first set according to the first selection rule;

The first set is a set of all front-end modules; the first selection rule is to select the front-end module with the highest current priority according to the priority order of the front-end module; the third antenna module is the antenna module currently used by the first front-end module.

The function ranking module 5023 is used for the formulation of the first selection rule. Regarding the formulation of the first selection rule, the following two priority schemes are included.

Option B1:

The function ranking module 5023 first determines the front end modules that are being used in all front end modules.

Specifically, how the function sorting module 5023 determines that the front-end module is in the "in use" state is various, for example, the mode 1: the function sorting module 5023 can identify the front-end module that the current screen is displaying as " "Used"; or, the front-end module directly associated with the currently displayed application interface is identified as "in use"; mode 2: the function sequencing module 5023 obtains the data transmission requirements of all front-end modules, and the demand therein is large The front-end module at a certain threshold is identified as "in use"; mode 3: the function sequencing module 5023 identifies all front-end modules that are being executed in the background of the smart terminal as "front-end" modules.

The function ranking module 5023 next sets the priority of the front-end module being used to be highest in the front-end module priority order.

Specifically, if there are multiple front-end modules in use at the same time, the function sorting module 5023 needs to further distinguish the priority order between the front-end modules that are being used. Here, a possible implementation manner is given: the function sorting module 5023 The priority is determined by the preset priority order. For example, the priority order of the front-end module when pre-configured is the call module>WIFI communication module>data network module>GPS positioning module; if the call module, WIFI communication module, data access When the module and the GPS positioning module are used at the same time, the function sorting module 5023 firstly matches the optimal antenna module to the calling module in the manner of the above embodiment, and then the WIFI communication module matches the optimal antenna module according to the preset priority order. All but the front-end modules used before match the optimal antenna module.

It should be noted that there are multiple possibilities for the pre-configured mode: mode 1, using the factory preset, the prioritization level of all front-end modules preset by the function sequencing module 5023 before the smart terminal leaves the factory; mode 2, user manual configuration function The sorting module 5023, according to the specific use environment or habit, when the user is dissatisfied or unsuitable for the priority level of all the front-end modules preset by the smart terminal before leaving the factory, the user can re-prioritize all the front-end modules according to the specific use environment or habits. The level is set; according to the user through the function sorting module 5023, the priority level can be determined and determined, and the front-end module with the highest priority level among all the front-end modules that are being used can be determined. .

For example, when the user is in the WIFI environment for a long time, and often uses the WIFI module for data call, the user can set the priority level of the front-end module through the function sorting module 5023 as follows: WIFI communication module>call module>data network module>GPS positioning Module.

Optionally, due to different usage scenarios, the foregoing pre-configured priorities may be switched according to usage policies of different scenarios. For example, according to the moving speed of the smart terminal, it can be divided into a low-speed moving scene and a high-speed moving scene; in the low-speed moving scene, the pre-configured priority is: WIFI communication module>data internet module>call module>GPS positioning module; In the scenario, the pre-configuration priority is: Call Module > Data Internet Module > WIFI Communication Module > GPS Positioning Module. This embodiment includes, and not only includes, a smart terminal for a scene mode, such as a tunnel mode, a rain and snow mode, and the like. The state of each antenna module can be detected and recorded in real time. The user can switch and adjust the antenna module and the front-end module in a pre-configured manner or manually configured by the user, thereby improving user experience.

Option B2:

The function ranking module 5023 first obtains the current start time of each front end module.

Next, the function sorting module 5023 sorts the front-end module priority order from low to high according to the order of the current start time of each front-end module.

For example, when the current usage time of the WIFI communication module, the data internet module, and the GPS positioning module that the user is using is: data internet module, WIFI communication module, and GPS positioning module, the front end module set by the function sorting module 5023 takes precedence. The order of the order is: data internet module <WIFI communication module <GPS positioning module.

In addition, in the solution, if the intelligent terminal determines in the background that the current start time of the two or more front-end modules is the same, the function sorting module 5023 determines and determines according to the priority levels of all the front-end modules that have been preset before the smart terminal leaves the factory. The front-end module with the highest priority among all the front-end modules that will be in use.

The first determining module 5021 confirms that the third antenna module meets the trigger switching condition, and specifically includes:

The first determining module 5021 determines whether the power difference value between the first antenna module and the third antenna module is greater than or equal to a power difference threshold.

The first judging module 5021 operates as follows:

During the sampling period, the first determining module 5021 determines whether the received signal strength value of the third antenna module exceeds the antenna received signal strength threshold or the transmit power value of the third antenna module exceeds the antenna transmit power threshold.

When the received signal strength value of the third antenna module exceeds the antenna received signal strength threshold or the transmit power value of the third antenna module exceeds the antenna transmit power threshold, the first determining module 5021 confirms that the third antenna module satisfies the trigger switching condition.

In this embodiment, when the received signal strength value of the third antenna module does not exceed the antenna received signal strength threshold, and the transmit power value of the third antenna module does not exceed the antenna transmit power threshold, the first determining module 5021 Then, it is confirmed that the switching of the antenna module is not required for the first front end module;

In this embodiment, the first determining module 5021 is configured to determine whether the antenna module that the first front-end module is using needs to be switched, and the determining module can provide a guarantee for the front-end module to correctly perform re-matching of the new antenna module.

The antenna matrix management switch unit is configured to acquire a first antenna module corresponding to the first front end module.

When the first antenna module satisfies the switching condition, the antenna matrix management switch unit controls the first front end module to match with the first antenna module, and performs data interaction through the first antenna module.

The first front end module is a front end module selected from the first set according to the first selection rule; the first set is a set of all front end modules; the first selection rule is to select the front end module with the highest current priority according to the priority order of the front end module.

The first antenna module is an antenna module selected from the second set according to the second selection rule; the second set is a set of all antenna modules; and the second selection rule is to select an antenna with the highest current priority according to the priority order of the antenna module. Module.

In this embodiment, the antenna sequencing module 5024 performs the order of priority of the antenna modules according to the average intensity value of all the antenna modules in the sampling period to form an antenna module priority order.

The average intensity value of each antenna module is as follows:

The second judging module 5022 mainly functions to avoid switching the antenna module too frequently. Contains the following two scenarios:

Option C1:

The second determining module 5022 determines whether the power difference value between the first antenna module and the third antenna module is greater than or equal to the power difference threshold:

Where avgRSSI _optim is the average of the received signal strength of the first antenna module during the sampling period, and avgTX _optim is the average of the transmit power of the first antenna module during the sampling period;

When greater than or equal to the power difference threshold, the second determining module 5022 determines whether the expected switching time of the first antenna module is less than a threshold period.

Specifically includes:

when

When the power difference threshold is used, the second determining module 5022 determines whether the expected switching time of the first antenna module is less than a threshold period; wherein the expected switching time T1 is:

Among them, bwt--antenna dwell time.

The smaller, the larger the bwt.

Option C2:

When the expected switching time of the first antenna module is greater than or equal to the threshold period, the first front end module does not satisfy the trigger switching condition, and the second determining module 5022 confirms that the first antenna module and the third antenna module continue to perform data interaction, and the operation ends.

When less than the threshold period, the second determining module 5022 confirms that the third antenna module satisfies the trigger switching condition.

The second determining module 5022 determines whether the received power level difference value between the first antenna module and the third antenna module is greater than or equal to the received power level difference threshold.

When the received power level difference value between the first antenna module and the third antenna module is smaller than the received power level difference threshold, the second determining module 5022 confirms that the first front end module does not satisfy the trigger switching condition, and the first antenna module and the first antenna module The three-antenna module continues the data interaction and the operation ends.

When greater than or equal to the received power level difference threshold, the second determining module determines 5022 whether the expected switching time of the first antenna module is less than a threshold period. In the solution C2, it is determined whether the expected switching time of the first antenna module is less than the threshold period and is consistent with the criterion in the above solution C1.

When the expected switching time of the first antenna module is greater than or equal to the threshold period, the second determining module 5022 confirms that the first front end module does not satisfy the trigger switching condition, and the first antenna module and the third antenna module continue to perform data interaction, and the operation ends.

As shown in FIG. 9 , for a specific antenna matrix management switch unit 502 , a plurality of front end modules and a plurality of antenna modules are connected to the antenna matrix management switch unit 502 through a circuit, and the highest priority front end is determined according to the above technical solution. The module, the antenna matrix management switch unit 502 adaptively switches the highest priority front end module to the current optimal antenna module.

First, the function sequencing module 5023 uses the first selection rule to determine the front-end module with the highest priority as the first front-end module. Secondly, the antenna sequencing module 5024 adopts the second selection. The rule determines that the antenna module with the highest priority is the first antenna module, and the first determining module 5021 determines whether the first front end module needs to be switched to the first antenna module. Finally, when it is determined that the switching needs to be performed, the second determining The module 5022 controls the first front end module to perform matching communication with the first antenna module; improving communication stability and reliability. This embodiment discloses the priority ordering rules of the front-end module and the antenna module, improves the reliability and stability of the antenna module switching, ensures that frequent invalid switching is not performed, and ensures that one antenna module is significantly better than the other antenna. When the module is in the module (for example, affected by blocking or multipath fading, etc.), the matching communication between the optimal antenna module and the optimal front-end module can be quickly realized.
